Long County coroner Emmett Patterson told the Associated Press a body found today in a wooded area near a rural highway was identified as that of 42-year-old Lori Arrowood.
Georgia Bureau of Investigation special agent Micah Ward says authorities have arrested Kenneth Lumpkin, a corrections officer in neighboring Liberty County.
Ward says Arrowood and Lumpkin knew each other. He declined to discuss any motive or say how she was killed.
Authorities say Arrowood's husband is an Army soldier serving in Iraq. Her 17-year-old daughter reported her missing Saturday.
Georgia Bureau of Investigation special agent Micah Ward said the arrest was based on interviews with Lumpkin following the officer's arrest.
Arrowood had been scheduled to attend a horseshow in Long county but never arrived.
Her daughter, 17, was the last person to see her before she left her home.
For the past three days, soldiers from Fort Stewart and community members have searched for Arrowood in the wooded area around her home.
